Across
  1. 2. Gives a white appearance to the nerve fiber-hence the term white matter of the brain and most peripheral nerves.
  2. 5. Containing the nerve fiber tracts with myelin sheaths.
  3. 7. Microscopic branching fiber of nerves cell that is the first part to receive the nervous impulse.
  4. 8. Containing cell bodies and dendrites.
  5. 10. It conducts impulses between the spinal cord and the cerebrum; incoming sensory messages are relayed through the thalamus to appropriate centers in the cerebrum.
  6. 12. Microscopic fiber that is part of a neuron and carries nervous impulse along a nerve cell.
  7. 13. Organ that receives and transmits a stimulus to sensory nerves.
  8. 14. Connects the spinal cord with the rest of the brain.
Down
  1. 1. Posterior part of the brain that coordinates muscle movements and maintains balance.
  2. 3. Type of glial (neuroglial) cell that transports water and salts from capillaries in the nervous system.
  3. 4. Nerves outside the brain and spinal cord: cranial, spinal, and autonomic nerves.
  4. 6. Largest part of the brain; responsible for voluntary muscular activity, vision, speech, taste, hearing, thought, and memory.
  5. 9. Are three layers of connective tissue membranes that surround the brain and spinal cord.
  6. 11. Connective and supporting tissue of an organ.
  7. 15. Is an individual nerve cell, a microscopic structure.
